[QUOTE="fdlsys, post: 949850, member: 2310"] 10" arm objectively has lesser need for anti-skating compensation because its tracking error is smaller because the diameter of the tracking arc is bigger. On 12" and longer radial arms it was common, right or wrong, not to bias them at all. In studios, when they felt they had the need for anti-skating, they dealt with in a most primitive but efficient way - lean the turntable slightly to the right and you get the mass of the arm to act as bias mass. First tonearms that I know that used this trick were B&O with their first dynamic VTF (simple linear spring) arm. The vertical gimbal axis is slightly off 90 deg, leaning to the right, so the mass of the arm always pulls to the outside. That also meant that the higher the dialed VTF (spring pull), the higher the effective anti-skating force would be. And since the arm catered only for their own fixed mass cartridges, there were no other factors but the mass+VTF to affect the pull force. Pure B&O genius. [/QUOTE]
